Frequently asked questions
What are the benefits of omega-3 fatty acids?
Omega-3 has anti-inflammatory properties and may help to support the circulation and immune system. Increasing omega-3 intake has been associated with an improvement in certain signs and symptoms, such as:
-Fatigue and muscle weakness
-Poor attention and/or concentration
-Dry skin, brittle hair, and thin nails
What can I do to improve my levels?
If the results of your omega blood test are outside of the healthy ranges, you may be able to make improvements with changes to your diet. This should include reducing the amount of omega-6-rich food you eat, while boosting your sources of omega-3s.
If you want to improve your Omega-3 Index, you’ll need to boost your intake of EPA and DHA. Oily fish, like salmon and mackerel, is one of the best sources. But if you don’t eat fish, you can increase your intake of algae like seaweed, nori, spirulina, and chlorella.
You may also be recommended to take a supplement, such as an omega-3-rich fish oil or algae supplement. If so, follow your doctor’s advice carefully.
Research suggests that not all omega-6s cause inflammation and some may even be anti-inflammatory. Also, not all omega-3s may be equally as good for you as one another. Some sources of omega-6 are healthier than others, such as sesame and avocado oils, which contain lower levels of omega-6 than sunflower oil.
Are all omega-6 fatty acids bad?
Yes, you can do an omega check with our at-home omega-3 blood test. We’ll send you everything you need including our omega-3 test kit and a pre-paid return envelope for your sample.
Can I take an omega-3 test at home?
Our essential fatty acids test includes a full lab analysis of your sample. You can view the results of your omega test on your MyMedichecks dashboard, with doctor’s advice on any next steps.
How can I test for omega-3 at home?
The Omega-3 Index test explained
There’s growing evidence that too much omega-6 is not the main problem with typical Western diets, but more so, the problem is too little of the beneficial omega-3 fatty acids, EPA and DHA.
The Omega-3 Index specifically measures the proportion of EPA and DHA in your blood — giving you an indication of your omega-3 status and your risk of heart disease.
Your result is given as a percentage, which indicates your heart disease risk as follows:
|Risk level||Omega-3 Index result|
So, once you know your index result, you can take steps to optimise it with some simple dietary changes.
Essential fatty acids and plant-based diets
Plant-based sources of omega-3s are not thought to have the same benefits to your heart health as those found in fish. And so, it can be harder to get beneficial omega-3 fatty acids into your diet if it’s plant-based.
However, there are ways to boost your omega-3 intake on a plant-based diet, including eating omega-3-rich foods like hemp and flaxseeds.
Omega-3-rich algae supplements can help you improve your omega-3 status (algae is the source from which oily fish get omega-3). Find one that contains both the omega-3 fatty acids, EPA and DHA.
And you can also cut back on omega-6-rich foods like sunflower and sesame oils to improve your 6:3 ratio.
